This is program to control AMD Overdrive settings that is working if graphics cards are in console-mode. This program has been written to replace amdconfig utility and allow to overclock Radeon GPU's if no running X11 server. An amdconfig utility requires a running X11 server and X11 kept configuration to be working correctly. Thus, this program ease overclocking of Radeon GPU's under console environment (in SSH or Linux console). Nevertheless, this program can works under X11 environment.


This program changes graphics card's clocks and voltages. This program can easily DAMAGE your hardware if it will be used CARELESSLY.

Before any setting of AMD Overdrive parameters (clocks, voltages, fan speeds), please STOP ANY the GPU computations and the GPU renderings.


Preliminary requirements

Program to work requires following things:

  • C++ environment compliant with C++11 standard (libraries)
  • pciutils library (libpci).

Optional components that can be used by program for AMD Catalyst drivers:

  • OpenCL environment (to force initializing of devices)
  • library (AMD ADL library)
  • ncurses library to coloring and bolding terminal outputs

To build program you need:

  • compiler compliant with C++11 standard
  • OpenCL headers (for AMD Catalyst drivers)
  • AMD ADL SDK (in site) (for AMD Catalyst drivers)
  • pciutils developer package (includes)

Building program

If you want to use amdovc with AMD Catalyst drivers, you should enable ADLSDK by replacing line in Makefile:




and you should set correct place of the ADLSDK in Makefile in line:

ADLSDKDIR = /home/mat/docs/src/ADL_SDK9

by replacing /home/mat/docs/src/ADL_SDK9 by your correct path.

You can also disable or enable terminal output coloring and bolding by disabling TERMINFO in Makefile by setting HAVE_TERMINFO variable:


Now. To build program, just type:


Invoking program

NOTE for AMD Crimson/Catalyst drivers): If no X11 server is running, then this program requires root privileges.

NOTE for AMDGPU(-PRO) drivers: Any parameter settings requires root privileges.

To run program, just type:


This command prints current status of all adapters (graphics cards).

./amdcovc -v

Prints more informations about graphics cards.

To print help, type:

./amdcovc -?

To set core clock and memory clock for first adapter, just type:

./amdcovc coreclk:0=1000 memclk:0=1200

Sets core clock to 1000 MHz and memory clock to 1200 MHz.

Understanding info printed by program

The AMDCOVC by default prints following informations about graphics card:

Adapter 1: Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP]
  Core: 1010 MHz, Mem: 1235 MHz, Vddc: 1.21 V, Load: 98%, Temp: 67 C, Fan: 54%
  Max Ranges: Core: 150 - 1050 MHz, Mem: 75 - 1450 MHz, Vddc: 0.8 - 1.225 V
  PerfLevels: Core: 300 - 1010 MHz, Mem: 150 - 1235 MHz, Vddc: 0.825 - 1.21 V

The first line below adapter is current state of graphics card (core clock, memory clock, voltage, load, temperature and fan speed). The new version add additonal info about device topology (for example PCI 3:0:0).

The PerfLevels is current performance level settings from lowest to highest. Ofcourse, the highest performance levels is used while some computations/rendering. First level will be used in idle mode (if no work).

The Max Ranges is minimal and maximal possible settings for graphics card.

For AMDGPU mode, the AMDCOVC prints:

Adapter 2: Ellesmere [Radeon RX 470/480/570/580]
  Core: 300 MHz, Mem: 300 MHz, CoreOD: 0, MemOD: 0
  PerfCtrl: auto, Temp: 42 C, Fan: 31.7647%
  Core Clocks: 300 608 910 1077 1145 1191 1236 1290
  Memory Clocks: 300 1750

Likely as in AMD Catalyst mode, an AMDCOVC prints core and memory clocks, but also prints core and memory overdrive factors (0-20). The PerfCtrl is current performance control (can be low, manual or high). The line Core Clocks contains all possible clocks for core. The line Memory Clocks contains all possible clocks for memory.

The verbose informations contains:

  • current state of graphics (Current CoreClock,...)
  • minimal and maximal fan speed settings
  • minimal and maximal clocks
  • minimal and maximal voltages (only AMD Catalyst mode)
  • current performance level settings (only AMD Catalyst mode)
  • default performance level settings (only AMD Catalyst mode)

also, in AMDGPU mode:

  • list of possible core clocks
  • list of possible memory clocks

List of parameters

List of parameters that can be set:

  • coreclk[:[ADAPTERS][:LEVEL]]=CLOCK - set core clock in MHz
  • memclk[:[ADAPTERS][:LEVEL]]=CLOCK - set memory clock in MHz
  • ccoreclk[:[ADAPTERS][:LEVEL]]=CLOCK - set current core clock in MHz (AMDGPU)
  • cmemclk[:[ADAPTERS][:LEVEL]]=CLOCK - set current memory clock in MHz (AMDGPU)
  • coreod[:[ADAPTERS][:LEVEL]]=PERCENT - set core clock in percents (AMDGPU)
  • memod[:[ADAPTERS][:LEVEL]]=PERCENT - set memory clock in perecents (AMDGPU)
  • corepl[:[ADAPTERS][:LEVEL]]=LEVEL - set current core performance level (AMDGPU)
  • mempl[:[ADAPTERS][:LEVEL]]=LEVEL - set current memory performance level (AMDGPU)
  • vcore[:[ADAPTERS][:LEVEL]]=VOLTAGE - set Vddc voltage in Volts
  • icoreclk[:ADAPTERS]=CLOCK - set core clock in MHz for idle level
  • imemclk[:ADAPTERS]=CLOCK - set memory clock in MHz for idle level
  • ivcore[:ADAPTERS]=VOLTAGE - set Vddc voltage in Volts for idle level
  • fanspeed[:[ADAPTERS][:THID]]=PERCENT - set fanspeed in percents

Extra specifiers in parameters:

  • ADAPTERS - adapter (device) index list (default is 0) or all for all adapters
  • LEVEL - performance level (typically 0 or 1, default is last)
  • THID - thermal controller index (must be 0)

The adapter's list can be a single number (0), a single range (0-1) or list of numbers and ranges, or all specifier (choose all adapters).

You can use 'default' in value place to set default value. For fanspeed 'default' value force automatic speed setup.

To overclock graphic card on AMDGPU(-PRO) driver, can you use coreod and memod parameters. Parameters coreclk and memclk is available in AMDGPU(-PRO) driver mode.

AMDCOVC under AMDGPU(-PRO) the coreclk and memclk paramters sets GPU core overdrive and a memory overdirve parameters which determines overclocking in percent. These paramaters does not impact on current GPU and memory clocks, but these paramters impact on their maximal values of clocks. To underclock core and memory you should use ccoreclk and cmemclk parameters or corepl and mempl parameters. These parameters set current core and memory performance level. The value default sets default automatic performance control.

List of options

List of options:

  • -a, --adapters=LIST - print informations only for these adapters
  • -v, --verbose - print verbose informations
  • --version - print version
  • -?, --help - print help

Text styling and coloring

By default AMDCOVC uses text coloring and styling (bolding) if the terminal/console able to display colors or text styles and if output is not the standard output/error. Following environment variables control whether coloring or text styling will be used:

  • AMDCOVC_NOCOLOR - disables coloring
  • AMDCOVC_NOBOLD - disables text bolding

Set value of an environment variable to '1','on','y','true','t', 'on' or 'enable' to enable its function. For example just try by running AMDCOVC in following way:

You can’t perform that action at this time.
